摘　　要：用4个甘薯品种的茎尖为接种材料,进行甘薯脱毒快繁培养基的研究。结果表明:最佳的茎尖分化培养基为MS+6-BA 0.5 mg/L+NAA 0.2 mg/L;最佳试管苗切段快繁培养基为1/2 MS(2/3琼脂+1/3食用胶+白砂糖)。茎尖分化成苗率高20%,快繁培养基成本降低45%,苗壮。With four varieties of sweet potato stem tip as vaccination materials, the optimal media for sweet potato detoxification rapid propagation were studied. The results showed that the best medium for stem tip differentiation was MS＋6-BA 0.5 mg/L＋NAA 0.2 mg/L and the best rapid propagation medium for the cuts of test-tube plantlet was 1/2 MS （2/3AGAR＋1/3 of edible glue;sugar）. Stem tip differentiation rate was 20%higher than the other treatments, and the cost of rapid propagation medium was reduced by 45%.
